Modifications Of SPH Towards Three-dimensional Simulations Of An Icy Moon With Internal Ocean
There are some traces of the existence of internal ocean in some icy moons, such as the vapor plumes of Europa and Enceladus. This implies a region of liquid water […]

Volatile-rich Sub-Neptunes as Hydrothermal Worlds: The Case of K2-18 b
Temperate exoplanets between the sizes of Earth and Neptune, known as “sub-Neptunes”, have emerged as intriguing targets for astrobiology. It is unknown whether these planets resemble Earth-like terrestrial worlds with […]

The Evolution Of A Young Ocean Within Mimas
The fractured, young surfaces on confirmed ocean worlds such as Europa and Enceladus suggest that ocean-bearing moons with relatively thin overlying ice shells should be easy to identify. Hence, the […]
